Macro- and microcirculation patterns of intrahepatic blood flow changes in patients with hereditary hemorrhagic telangiectasia

Figure 3 Arteriovenous hepatic malformation (shunt) in a 49-year-old woman. Color coded Doppler sonography and Power Doppler images. A: Intrahepatic arterial hypervascularization with tortuous hepatic artery and aliasing in segment IV (central) and VIII of the liver as well as obvious presence of left accessory artery. Enhanced mean diameter of the hepatic artery (8.2 mm) intra- and extrahepatic and increased peak systolic velocity (245.7 cm/s) and end-diastolic velocity (85.9 cm/s); B: Image of the portal vein of the same patient, showing increased peak flow velocity (27.9 cm/s) but without elevation of the mean diameter and without signs of portal hypertension. Caselitz-Kriteria: 2 Major + 3 Minor; Buscarini grade 2; no color spots in peripheral regions.
